As always we are gonna look at three most important characteristics of the window:—Beauty — Reliability, Performance and Warranty

Beauty

The window frame and sashes are made from virgin vinyl. When you look at the window, you can see pure white color. When bluish color is present, it means that the window is made from recycled vinyl.

The window has balance covers. Some other window manufacturers neglect that one small detail. After some time spider web and dust accumulates inside the balance channel and it is not easy to clean it

The window has low recessed sash lock. The design of the lock makes the replacement window look more stylish and modern

The combined sash and the frame thickness is acceptable. This window can be installed into the house with small windows without a glass area loss.

The Exterior of the window has a rounded beautiful screen channel. It gives a wood window look for the window.

Reliability, Performanceand Warranty

Okna Insul-Tec Windows have Block and Tackle Balance System.It is low maintenance and durable. The window can be opened and closed for about 28,000 time, before the balance system fails.

The window has triple layer of weather stripping on both sashes. There is an air bulb on the top sash meeting rail. When you close this window, there is no chance that any air is going to get into the house or out of the house without your permission

This window has thick air bulb on the bottom sash. That makes the window sash shut like a door of a fridge.

Okna Insul-Tec does not have weep holes. The window has a fusion welded sloped sill, so all the water drains from the sill to the outside. The weep holes get clogged with spider web and dirt. If that happens the water stays inside the frame of a window and may get inside the house.

Well made night latches are standard. It is a nice feature to have in a vinyl window especially when you have pets or kids in a house. You can lock the window sash with a 3” opening space.

The window has Lifetime Limited Warranty. It covers all the locks and moving parts of the window for as long as you own the house. The glass of the window has a lifetime coverage as well.

What could be done better in that replacementwindow

The Screen frame of the window is made from a rolled formed aluminum, which is not that durable

OKNA window company provides Lifetime Limited Warranty. We all like the word “lifetime”, but what about that nasty one “limited”. Let’s see how Okna Windows and Doors warranty works.

The vinyl frame and vinyl components of the OKNA replacement windows and sliding doors are warranted to be free from defects that might result in blistering, flaking, corroding and fading of the window or a sliding door. You get this coverage from the date Okna windows installed into your house. You are covered as long as you own the house. Plus this warranty is fully transferable to the next home owner as well. Which is very generous allowance. Usually other window companies do not allow transference of the warranty or allow it for the next 20 years only.

Okna Windows company warrants that insulated glass unit is gonna be free from obstruction between the glass, including moisture on the internal glass surfaces caused by seal failure. This warranty is lifetime for the first homeowner and it is transferable for the next one as well. Most other companies give 10-20 year non transferable warranty on a glass. Glass stress cracks are covered for one year only. If your glass has mini blinds between the glass panes, then the warranty is 10 years only.

Hardware of the replacement window has a lifetime warranty as well. Okna Windows company warrants that all hardware shall remain in good working condition, for as long as you own your house. It is fully transferrable to the next homeowner as well.

All of the above was that “Lifetime” warranty. Now let’s talk about the “Limited”. Under thelimited part of the warranty, there are some cases when the warranty is 10 years only. When you order Okna replacement window with a special color, the window is gonna be painted. The Okna Window company gives 10 years warranty on that paint only. The same thing is with hardware with custom paint coating. It is warranted 10 years only.

Now, let’s see what should you be looking for to talk well with the Okna Customer care. The only thing you need to find is a warranty sticker, whichis located on the sides of the bottom and top sashes. If after some time these stickers discolored and peeled off, then check the top channel of the window frame. There is one more warranty sticker there.

So all in all Okna Windows and Doors Company provides solid warranty and surpasses in many cases the warranties of their competitors. If you want to print out Okna window warranty, feel free to do so by downloading the file at the bottom of the post. This is updated warranty by OKNA Windows Company as of October 2018.
